Sorry to hear about the crash but I'm glad you didn't get hurt seriously other than the Racetrack Rheumatism.
Explain to your insruance company what happened and go to court with the ticket to plead your case. Get pictures of the scene if possible showing any and all skid marks. Draw up a good poster size diagram of the roadway and exit ramp with all vehicles designated. You might even have reasonable cause to file suit against the other driver. If he sues you, countersue him. You might even get lucky and have the insurance company sick a few of their attorneys of the other guy, but I wouldn't hold my breath.
Next thing I would do is to have them tow the truck to my home if you have enough room and your neighbors wouldn't get too offended or there are any zoning regs to prevent it. Barring that, I would GO IMMEDIATELY to where the vehicle is being stored to take pictures of anything that isn't permanently welded to the truck. This is just in case some bozo does to you what happened to me, remove parts with or without permission.
Gather up every receipt you have on anything you have had done to the truck, even if it is only Preventative maintenance. Contact your insurance company to discuss what they will and will not reimburse you for in regards to extraneous equipment which they will undoubtedly claim adds no intrensic value to the resale of the vehicle had it not been wrecked ie: aftermarket tires & wheels, bumpers, lift kits, and BOMBING upgrades to the engine. Winches, repair work, such as a new transmission or other large ticket repair items and the like do add such value, but you will have to argue that point vehemently.
Either get a hard copy of NADA book, or check online for the NADA resale value of the truck. Start with the most expensive price in the book for your truck. The insurance company will try to Lowball you with the cheapest price they can. Make them give you retail not wholesale NADA value or find you a comparable truck with identical equipment depending on the options.
When settling make them itemize EACH AND EVERY single aftermarket item for which their settlement covers so you can remove all the other goodies for which they refuse to reimburse you. If they refuse, tell them you intend to strip the truck of everything possible. If they still refuse, argue that the property is yours to do with what you will unless they reimburse you in full. Thats why you need the receipts, to prove that the property belongs to you. Call the police if need be and have them meet you at the holding yard as you remove your rightful property with receipts in hand and the Title to the truck.
Thats about all I can think of for you to do offhand. I hope you make out at least as good as I did just before I got my Ram. I had an 11YO Toy 4Runner w/145k miles that I got $7000 for and I got my truck back. The winch, brush guard, Barometric Altimeter, and Level Gauge on the dash was stolen at the impound yard for which I had to separately sue the impound yard owner to recover the cost of those items, another $1200 for a TTL of $8200 for a well used truck that can still run with the aid of a cutting torch and two new wheels and tires.
Good luck and Kick some Insurance hiney for me!
